Dear René,
it seems to me that your problem is related to the presence of older -sfcross- version(s) in your Stata directories.
My advice is to search for the current -sfcross- and -sfpanel- installations using the following (in this example -sfcross- has ID 168)
===================Code Begins========================
ado, find(sfcross)
[168] package st0315 from http://www.stata-journal.com/software/sj13-4
SJ13-4 st0315. Stochastic frontier analysis...
===================Code Ends==========================
and then uninstall them by typing
===================Code Begins========================
ado uninstall [168]
===================Code Ends==========================
or, in general, by typing
===================Code Begins========================
ado uninstall [ID_of_the_command]
===================Code Ends==========================
Then, you will be able to install the last version of the package by typing
===================Code Begins========================
net install st0315.pkg
===================Code Ends==========================
You can also find it useful to download the last version of the accompanying paper published in the last issue of SJ
http://www.stata-journal.com/article.html?article=st0315
Hope this helps,
Federico
